U-R is another robot helper on Primus. He is Gleep's best friend, who works for the Scientists Of Primus. They can track him down anywhere. He moves about on a pair of rolling treads, but can rear up to walk on a pair of legs at times if the occasion requires it.

Trivia (Clawful94): It is unclear who voiced the scarcely used U-R in the "New Adventures Of He-Man" cartoon series.
